Abstract
The invention relates to analytical chemistry, particularly to sorption methods for extraction of platinum metals. The extraction of platinum (II) and/or platinum (IV) is carried out by modified sorbent from chloride solution. As sorbent silica gel, modified with tetradecylammonium nitrate is used. The extraction is carried out at pH 0.5-4.0 correspondingly with 0.1 M solution of NaCl. The use of the process in comparison with analogue gives the possibility to increase extraction efficiency of platinum, reducing the extraction time, particularly for platinum (IV) in 4 times.
